We begin with the Grandfather-Father-Son (GFS) backup rotation model, explaining how it balances data redundancy and storage space. Then we dive into the 3-2-1 rule—keeping three copies of your data, on two different media types, with one copy off-site.We also explore full, incremental, and differential backups, as well as the importance of regularly testing restores to ensure recovery plans actually work when needed. These strategies often appear in scenario-based exam questions, where you’ll need to select the best approach for business continuity or disaster recovery.
